Very Short Run Times this morning

I have been so busy that I really haven't had time to check my on times with my ac. Well this morning it ran for 1 minute on like 50 off 2 minutes on and 30 off and 4 on with 30 off and 5 on with 30 off. Is there any way you guys think something is wrong with the stat? I don't see how the stat could get a 1 degree difference in 1 minute or even 2 minutes.

Yes I have a 1 year warranty with the system and house. They have been out 3 times now and keep saying nothing is wrong with the unit. They have checked pressures and temps and freon levels. They keep saying that it is just satisfying the thermostat so it kicks on and off quick. The load calc came out to me needing a 3.75 ton so they went with a 4 ton instead of a 3.5 ton system. A pro did install it with a great reputation around town.

Early this morning you said it ran and kept getting short on/off times. Why would it run if your tstat is above the temp outside. Am I missing something here? So the temp has been below the tstat all morning I would assume. What am i missing here.
